The present invention relates to laundry equipment and more particularly to an improvement in extractors.

Some of the objects of the present invention are to pro-vide an improved extractor for more expeditiously removing liquidv Yfrom clothes, fabrics or other materials; to provide a novel means for mounting the rotary basket or element of an extractor whereby stresses and strains are lessened and vibration reduced to a minimum; to provide a new and original secrtional container for holding the material in an extractor; to provide an improved material container wherein provision is made for quickly dumping the contents of the container; to pro'- vide a material container which can be packed for shipment in a minimum space; to provide a container for an extractor wherein the construction allows for automatic expansion thereof when subject-ed to centrifugal force; and to provide other improvements as will hereinafter appear.

In the accompanying drawings Fig. l represents a perspective of an extractor embodying one form of the present invention and showing a novel material container in position for lowering into the extractor; Fig. 2 represents one unit of the container in assembled condition; Fig. 3 represents the same in knock-down form for shipment; Fig. 4 represents a section on line fi--t of Fig. 2 Fig. 5 represents the unit of Fig. 2 in discharge position; Fig. 6 represents a sectional elevation of the extractor showing a modifled form of container in elevation and partly lowered towards extracting position; and Fig. 7 represents a perspective 0f the container shown in Fig. 6.

Referring to the drawings one form ofthe present invention consists of a casing or curb IEB, of open top cylindrical shape, which is supported in the usual manner upon spring hangers Ii from fixed stanchions I2 anchored to a suitable base. As here shown a truss-like frame I3' is riveted or otherwise made fast to the outside of the bottom i!! of the casing itl and serves as a rigid mounting for a bearing I5 in which the vertical driving shaft I5 is stepped. This shaft IB extends into the casing It and terminates in a face plate I'l to which the rotary basket I8 is made fast. Preferably an annular track 20 is mounted upon the inner face of the bottom IA and the rotary basket I3 travels thereon through the medium of anti-friction rollers 2I. The basket I8 is of the usual perforated construction having an open top for the reception, in this instance, of a novel form of material container, instead of receiving the material directly as in the ordinary practice.

In Figs. 1 to 5 inclusive a form of container embodying the present invention is shown consisting of two half units 22 arranged to be assembled back to back for lowering into the extractor basket i8, but when so assembled being free to move relatively towards and away from each other. As these units are duplicates the present description will be confined to one and like parts in the other designated by like reference numbers.

The unit 22 is preferably formed of relatively heavy wire so interconnected and shaped as to form a rectangular frame 23 as a back, and upper and lower substantially semi-circular top and bottom bars 24 and 25 projecting from the same side of the frame 23. These bars 24 and 25 are interconnected by vertically disposed rods 26, the ends of each of which are respectively threaded for right and left hand screw action to enter correspondingly threaded socket eyes 21. As here shown there are five socket eyes 2l on the bar 24 and a like number on the bar 25,

cach opposite pair being joined by a rod 26 to L maintain the proper spacing between the bars 24 and 25, and to strengthen and reinforce the unit. The rear frame 23 as well as the curved front area of the unit is covered with wire mesh, or open-work cloth, or any other suitable material 28 capable of retaining the fabrics or goods to be centrifuged and permitting the water to pass therethrough for proper action.

In order to support the fabrics or goods in the unit, a liquid pervious bottom is provided preferably consisting of a perforated metal plate 2S hinged to the bottom bar of frame 23 and conforming to the shape of the unit bottom, so as to form a complete closure therefor. A hook 32 or other fastening means is provided to engage the bar 25 and lock the bottom in place as a support for the contents of the unit.

Since the units are designed to be handled by modern overhead travelling lift mechanism, lift rods 33 are permanently attached respective- `ly at one end to the lower corners of the frame 23 and incline towards the center of the top bar 24, where each is made fast by a clamp 34 to the aforesaid bar 24. Each of these secured rod ends terminates in an eye 35 projecting above the bar 24 in position to be easily engaged by hooks 3E of the lift mechanism 3l. Thus the mechanism 3l can be removably connected to the two eyes 35, and also to an eye 38 at the middle of the bar 24 so that the hanging weight will be equally distributed and no undue strains placed upon the fabric or other mesh body cover. When so suspended on the carrier mechanism 3l the lled units can be transferred from one place to another and for emptying the hook 32 is released from the bottom bar 25 whereupon the hinged bottom swings downwardly and allows the clothes, fabrics or other material to fall by gravity out of the unit. In connection with this dumping action attention is directed to the fact that while the upperbar 24 of the top of the unit may be either of rigid material or flexible, it is preferable to employ `arelativ-ely heavy flexible cable so that the lifting effort of the mechanism 3l will tend to draw this iiexible cable'24 inwardly toward the rear frame 23, as shown in Fig. 5. This performs a function not possible in the rigid u Vtype of construction because if any of Vthe materials or fabrics in the unit tend to Wedge or stick to the sides of the unit this drawing together of the top will press the material toward the open lbottom and ensure prompt and complete dis-V charge. Y The form of material holding unit shown in Figs. 6 and 7 consists of two semi-circular container baskets each formed of an upper metal rim 4E] and a lower metal rim 4l which are interconnected by vertical bars 42 and enclosed by a fabric Y, cover conforming to the shape of the metal frame-work; Each half of this unit is open at the top but provided Witha suitable bottom preferably fabric covered which is capable of being Yreleased for discharge purposes 'as will be understood. In'Y assembling the two container parts the opposed ilat surfaces are arranged in juxtaposed relation and the two upper semi-circular bars 4@ are'interconnected by means of pivoted links 45 and the lower semi-circular 'bars 4I are interconnected by links 46. The ends of these pairs of links are apertured to receive the respecl tive hook ends of a rod 41 and the end of each of these rods terminates in a hook 48 `by means of which the container can be engaged by the hoist-V ing mechanism for lifting it out of and lowering it into the extractor basket i8. ing movement the links 45 and 46 will collapse upwardly to draw the two halves of the container together so that it can be readily removed from Vor lowered into the basket I8, but whenvthe containerl is located in the basket I8 and free of the lifting mechanism the centrifugal action causes Y the links to spread with an kaction somewhat Y Vfor easy packing purposes.

Vsr'nilar to a toggle joint so that the two halves of the container move upwardly to seat flush against the inner wall'of the basket I8. VIt will therefore be noted that in both forms of the units either that Vof Figs. l to 5, or Figs. 6 and '7 there is Vprovision for the unit automatically expanding and seating tightlyV against the'inner periphery ofthe basket i8. This relieves the unit parts of the Yordinary strains received from a centrifugal action and yet the construction is such that units are automatically withdrawn radially as soon as the lifting mechanism starts to lift them axially. In each construction the normal diameter of these units is less than the inner diameter of the extractor basket l and consequently in either form the'units can be readilylowered or lifted out of the basket without interference.V Y

Another feature of the unit construction shown in Figs. 1 to 5 inclusive is the provision for com- K pact shipment, in that the brace rods and sup- Vport rods can'be removed, the top and bottom folded fiat against the rear frame, and the removable bars placed hat on the collapsed unit At the destination the rods can readily be replaced and the entire assembly shaped for use in a relatively short time.

During the liftv Yrewriting the extractor basket is the'shaft l0 in the present instance carries a pulley 50 driven by a belt 5I from a second pulley 52 associated with and driven byra m'otor 53.

While only two forms are shown in which this invention may be embodied, it is to be understood that theiinvention is not limited to any specific construction, but might be applied to various invention or the scope of the appended claims.
